Given that the coin has a conservation of 95 (S/C-), which is a very high conservation, and considering that it is the first time it is being auctioned, the starting price is 900 euros.

In general, coins in similar conditions tend to reach hammer prices that can be significantly higher than the starting price, especially if there is interest in the auction. Without historical sales data for this specific coin, it is difficult to make an accurate estimate, but it can be considered that the hammer price could be between 1.5 and 2 times the starting price, depending on the interest of collectors.

Therefore, an estimated maximum purchase price could be in the range of 1350 to 1800 euros. However, since there is no data from previous auctions, it is advisable to pay attention to the dynamics of the auction and the interest of the bidders.
